I am using them now, but headers are not any faster by SSL compression...Someone mentioned slow speeds, but GN has also been slow for some people at the same time.My connection is only 1.5mbps, so I haven't seen speeds slower than normal...The website isn't as refined as GN though, there's no way to find out retention on a group.The transfer statistics is basically the same though, just doesn't give a projected usage...To login securely you need this link.Login = email, so I would highly recommend the SSL account.
